Is Being Good at Math Genetic?

The previous post, "Are You Good at Math?", describes a study that groups twins according to math abilities. The study discovers that if one of the twins is found within the group of math achievers, it is very likely that the other twin also belongs to the same group. So, perhaps, being good at math is genetic. However, looking at the group of children who struggle in math, the study finds that having one of the twins not do well in math is not a guarantee that the other twin likewise finds math difficult.  Nevertheless, there is one trend generally seen, struggling in math correlates with anxiety in math.

The Association for Psychological Science has recently issued a press release:

Thus, there is a link between a child's math achievement and anxiety, and the math anxiety of the parents. This needs to be qualified, however, according to the study. It is not necessarily determined by genes. It has an environmental component. The link appears only when parents are oftentimes helping the child with his or her homework. It should be noted that what specifically a parent does that may cause a child to be anxious in math has not been addressed by the study. Nevertheless, it is obvious that there is a need for parents and educators to be made aware that math anxiety can likewise be developed at home.
